The 511 is a great choice for a multi-purpose utility knife, with a longer carbon steel blade. The plastic handle features a guard in front and a hooked pommel in the back, for a more improved grip, and is mostly symmetrical, so if will be equally comfortable if held with the blade edge facing up or down. The handle click-locks securely into the plastic sheath, and the sheath clips onto your belt.
Below are the detailed measurements of this knife. One important note: for best comfort and grip, the length of your middle finger should be similar to the circumference of the handle.
